1. Compute SHA-256 of OTSCanonicalRecord value → must equal OTSHash 2. Open OTSProofURL → extract Bitcoin block number → must equal OTSBitcoinBlock 3. GET OTSBitcoinBlockVerifyURL → returns the Bitcoin block hash at height OTSBitcoinBlock; GET https://blockstream.info/api/block/{that hash} → its timestamp must match OTSTimestamp 4. Read CopyrightID inside OTSCanonicalRecord → must equal the CopyrightID above 5. GET OTSVerificationAPI → pre-computed 6-check result from server 6. If all match: this entity was registered on CopyrightChains at OTSTimestamp, independently verifiable on Bitcoin Note: an OTS proof may carry multiple Bitcoin attestations; OTSBitcoinBlock is the earliest confirmed one — a later attestation inside the proof corroborates it and is not a mismatch

Wo Dil Hi Kia Jis Mei Samoya Nahi Hussain
Nabi Ka Lab Par Jo Zikar Hai Be Misaal Aya
Main Banda E Aasi Hun Khatakaar Hun Mola
Yeh Dil Bhi Hussaini Hai Ye Jaan Bhi Hussaini Hai
Hum Banawat Se Nahi Kehty Ke Hum Tere Hain
Ronday Umar Nibhai Yaar Di Khabar Na Kai
Arzoo Hai Ke Tera Gumbad-E-Khazra Dekhon
Milta Hai Kia Madinay Me Ik Baar Ja Ke Dekh
Pushton Main Hun Naseer Mangta Hussain Ka
Kainaat Tuk Mah E Tabaan Rahmat ul Lilalamin
Na Kaleem Ka Tasawar Na Khayal E Toor E Sina
